摘　　要：介绍了自行研制的中频离子氮化脉冲电源的结构.利用UC 3825B设计了中频离子氮化脉冲电源的逆变控制电路,同时设计了一种新的灭弧保护电路.该控制电路已成功用于离子氮化脉冲电源,解决了高频变压器的偏磁问题,保护电路能快速可靠地灭弧,灭弧时间约为2.5μs.This paper introduces the structure of mid-frequency plasma nitriding pulse power supply made by ourselves. An inverter control circuit for mid-frequency plasma nitriding pulse power supply is designed by using UC3825B,and a new protecting circuit for arc extinguishing is designed too. Experimental results demonstrate that the control circuit has been successfully used in mid-frequency plasma nitriding pulse power supply. The protecting circuit can extinguish arc quickly and reliably, and extinguishing time is about 2.5 μs.
